EYEGLASS-IVIOUNTINGL SPECIFIC A'IJION' forming part of Letters Patent No. 752,030, dated February 16, 1904.

Application filed April 25, 1903, Serial No. 154,357. (No model.)

To all whom, it may concern.-

Be it known that I, HARRY GAswELL, a citizen of the United States, Whose residence and post-office address is at No. 34:2 East Fiftyfifth street, in the city of Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement .in Eyeglass-Mountings, of which the following is a specification, reference being had to the accompanying drawings, in which 7 Figure 1 is a vertical view. Fig. 2 is a top view. Fig. 3 is an enlarged top view of the left half ofthe mounting, with dotted lines showing the position of movable parts when the eyeglass is on the nose, the full lines showing the position of the same parts when the glasses are being removed from the .nose or placed thereon. Fig. 4: is an enlarged view of the movable part detached from its connections.

The object of my invention is to provide a mounting which holds the lens rigid, so that the focus when once adjusted will not thereafter be changed by placing the glasses on the nose or by removing them therefrom; to provide for the attachment of any form of noseguard; to secure adjustable pressure on the nose-guards; to provide for adjustment on and removal from the nose without touching the lens; to simplify construction, and cheapen production.

In the drawings, A is a bar of any suitable size, strength, and material of the form preferably as shown in Fig. 2, the largest part being straight or slightly curved, the ends at B being so bent as to place the bar in such relative position to the lens that it will not touch the nose. On the ends of the bar A are clamps C, constructed to receive and hold the lens I). The inner part of each of these clamps is so formed as to constitute one-half of a pivotal joint, as shown by the dotted lines E in Fig. 3. A central hole in this part of each of the clamps is threaded to receive and hold a stud screw F. This hole is the center of the cir cular part B of the bar A. Attached to this part of each of said clamps by the stud-screw F are the levers Gr, each having an arm H, one side of which has a circular slot I, Fig. 4, adapted to fit and partly encircle the bar A, forming part of each of these levers, and at right angles to the radial arm is a nose-guard box J, constructed to receive and hold the nose-guard. On the bar A and between the lever-arms H is a coiled spring K, arranged to engage the slotted part of the arms and press them 7 apart, and thereby closing the noseguards.

I/Vhen the several parts are constructed as described, with the spring in place on the bar, the levers G are attached to the clamps C by sliding the slotted parts I of the lever-arms H into engagement with the bar B, as shown in Figs. 2 and 3, the coiled spring Kbeing compressed between the lever-arms. In this position the stud-screw F is inserted through the centralhole N in the levers G and the screw driven home into the joint E of the clamps C, on which the levers are free to be partly revolved, the movement being limited by contact of the slotted part of the arms H with the circular part B of the bar A. The ends M of the arms H are slightly curved to afford a secure hold by the thumb-and finger, by which the eyeglasses are placed on and removed from the nose without touching or disturbing the lens D.

What I claim as new, and desire to secure by Letters Patent, is

In the mountings for eyeglasses described, the combination of a pair of clamps C forming an integral part of a bar A, joining said clamps with a pair of levers Gr pivotally attached to said clamps by the stud-screws F, the long arm H of each lever having'a circular slot I through which the bar A extends, and a coiled spring K encircling the bar A between the lever-arms H, substantially as described and for the purposes specified.
